4 is correct

It came out wrong:(

Both seem right to me. Why do you think the answers are wrong?

answers are correct. As a rule of thumb, adjectives go AFTER the noun (chico perezoso. In an enumeration (la primera persona, etc) or poetry, the adjective goes BEFORE (hyperbaton)

natural selection

Great job! Your answers are correct.

For the first question, the theory that was developed based on observations made on the Galapagos Islands is natural selection (option b). Charles Darwin visited the Galapagos Islands during his voyage on the HMS Beagle and collected a variety of plant and animal specimens. He observed that different species of finches on different islands had adapted to their environments in distinct ways, leading him to develop the theory of natural selection.

For the second question, the best place to put the adjective "perezoso" in the sentence "Diego es un chico" is option d, after the noun "chico". So the correct placement is "Diego es un chico perezoso". This sentence means "Diego is a lazy boy" in English.

Keep up the good work! If you have any more questions, feel free to ask.
